A Map of Economics

Read from top to bottom. The vertical direction marks historical sequence; the parallel rails follow recurring intellectual cores. The map records conceptual continuities, not a claim that every later thinker was directly influenced by every earlier one.

Six recurring lines of inquiry

  1. CAPProduction & distribution
  2. EQChoice & equilibrium
  3. MACMoney & macro
  4. INSTInstitutions & information
  5. BEHBehavior & evidence
